From PCB design to mass production, Fanway delivers quick-turn PCB manufacturing services as one-stop solutions to address your diverse project requirements and accelerate your time-to-market.
Heavy Copper PCB (Thick Copper PCB) is a special circuit board designed for high current, high power applications, copper thickness of more than 20oz. At Fanway, we specialize in manufacturing Heavy Copper PCBs with perfect power handling, thermal resilience, and mechanical strength.
State-of-the-art facilities equipped for 4+ layer Heavy Copper boards, controlled impedance, and mixed-technology integration (HDI, rigid-flex).
ISO 9001, IATF 16949, and UL-certified processes with rigorous testing (AOI, X-ray, thermal shock).
Collaborate with our engineering team for design optimization, DFM feedback, and rapid prototyping.
Fast turnaround, competitive pricing, and end-to-end logistics—whether you need prototypes or mass production.
✅ High Current Capacity
Engineered to carry elevated currents without overheating, our Heavy Copper PCBs are good solution for power converters, motor controllers, and energy storage systems.
✅ Excellent Thermal Management
Thick copper layers dissipate heat efficiently, reducing hotspots and extending component lifespan perfect for high-temperature environments.
✅ Enhanced Mechanical Stability
Robust copper traces and plated through-holes withstand repeated thermal cycling, vibrations, and mechanical stress.
